Packages are correctly installed, but it fails to compile the project:
‘arm-none-eabi-g++’ is not recognized as an internal or external command, operable program or batch file.
Why is this happening? “.platformio/toolchain-gccarmnoneeabi” definitely contains the correct windows binaries. Without using custom platform_packages it works fine. Tried removing all .cache or .pio folder (as suggested in other threads), but same problem.
Oh, I just realized that tool-teensy\ only contains teensy.exe, but not all the other binaries. According to the guide (mentioned in the first post) I should copy over “Arduino15\packages\teensy\tools\teensy-tools”, but that in fact only contains teensy.exe as well. So seems that for the tool-teensy package there’s more to do than just copying the Arduino package folder. Not sure if I even need a new version of tool-teensy for the 1.59 Beta. Seems to work fine with the 1.58 package
Either the .exe is just plain corrupted, the location of the file within tool-teensy is incorrect, the location of the package.json is incorrect, or you’ve copied over a binary for a different architecture / operating system over, or the platform_packages declaration is wrong.
When you manually open a command terminal and drag-and-drop the Teensyduino 1.59 beta teensy_size.exe in it and press enter, do you at least get some output?
